Individual Response to Ionizing Radiation and Personalized Radiotherapy

Area of Science:

• Oncology
• Radiation Oncology
• Cancer Biology

Background:

• Radiation therapy is a cornerstone of cancer treatment.
• Current radiation therapy lacks personalization based on individual tumor and normal tissue biology.
• Implementing biology-driven approaches is crucial for optimizing treatment outcomes.

Purpose of the Study:

• To review the mechanisms of tumor radiosensitivity.
• To examine early and late normal tissue responses to radiation.
• To discuss the clinical implementation of biology-driven personalized radiation therapy.

Main Methods:

• Literature review of radiation response mechanisms in tumors and normal tissues.
• Analysis of factors influencing tumor radioresistance and normal tissue toxicity.
• Exploration of therapeutic opportunities for tumor radiosensitization.

Main Results:

• Understanding radiation response mechanisms is key to developing predictive biomarkers.
• Early and late responses of normal tissues vary and impact treatment planning.
• Personalized approaches can improve efficacy and reduce toxicity.

Conclusions:

• Biology-driven personalized radiation therapy holds significant promise for cancer treatment.
• Further research into radiation response mechanisms will facilitate clinical translation.
• Biomarker development is essential for tailoring radiation therapy to individual patients.
